Title : Stress level in patients in the preoperative period of bariatric surgery


Stress symptoms such as anxiety, depression, nervousness and the habit of eating when emotional problems are present are common in patients with obesity (Abeso, 2016). The objective of this research was to raise the level of stress in 136 patients with obesity in the preparatory process for Bariatric Surgery. We evaluated 92 women and 44 men aged 16 to 69 years, with a Body Mass Index (BMI) ranging from 30 to 58. Patients were evaluated between March 2021 and March 2022.

We used the instrument ISSL - Lipp's Stress Inventory (2005), which makes it possible to identify the stages of stress in which adults are: Alert, Resistance, Near-Exhaustion and Exhaustion. We found 56 women (60.86%) with symptoms of stress and 36 women (39.13%) without symptoms of stress. We found 25 men (56.81%) without symptoms of Stress and 19 men (43.18%) have symptoms of Stress.

In women with stress, 47 (83.92%) have symptoms of stress in the resistance phase, 5 women (8.92%) have stress in the alert phase and 4 women (7.14%) have symptoms of stress in the of exhaustion. In the majority of women who have symptoms of stress in the resistance phase, 27 (57.44%) have a predominance of psychological symptoms and 20 (42.55%) have a predominance of physical symptoms.

Among men who experience stress, 18 (94.73%) have symptoms of stress in the resistance phase and 1 man (5.26%) has symptoms in the alert phase. Of the men who present symptoms of stress in the resistance phase, 11 men 83.92%) have a predominance of physical symptoms and 7 men (38.88%) have a predominance of psychological symptoms. According to Lipp (2005), Stress is a reaction, with psychological, physical, mental and hormonal components, that the organism has in the face of any situation that represents a greater challenge. If the stress is continued, the body becomes overtired and the person starts to wear out too much.

In conclusion, we found that the majority of women 47 (83.92%) have stress in the resistance phase. Most men (56.81%) do not experience stress, but 19 men (43.18%) experience stress in the Resistance phase.
